And your car has power steering, a huge mechanical advantage courtesy of the linkage involved, a steering wheel instead of a handlebar and the two wheels aren't a few inches apart.
It's a fake HD semi truck, not a motorcycle, so what IS there to like? He copied a Peterbilt. What "vision" is required for that? It's a gimmick, a toy, not a motorcycle.
What I don't understand is your perceived feelings towards it/him. Maybe I'm wrong, but it sounds almost like you are angry or offended that someone has built something.
You are basically right about my car. 2 of the 3 cars in my driveway have power steering, and all three have wheels. OTOH, the track on all three can be measured in inches.
The "vision" is that AFAIK, at least, this is the only one in the world. IE "UNIQUE". He drew inspiration from a Peterbilt, perhaps, but I doubt that any single part is interchangeable. Having fabricated a few small parts, I have a large appreciation of the work and talent and again, vision, involved in taking an idea and then actually building it. Of course it isn't a "motorcycle". The Eiffel Tower isn't a motorcycle, either, but it took some brains and work to build it. Assuming the "HD Semi" actually works, it is more than a gimmick and a toy, but probably will never be used as a daily, long-haul commercial carrier.
To restate, whoever built it is more talented than I am, and I respect that, even if I would not use my talents to build the same thing even if I could. I just don't get why it would make anyone angry.
